EXPLOSIONSSCHUTZVENTIL

Disclosed is an explosion protection valve comprising a closing member (4) which is movable inside a housing (2), is guided along a guide bar (3), and can be displaced in a moving direction from a predefined open position into a sealing closed position in case of a shock wave or suction wave. The explosion protection valve further comprises a spring arrangement that is effectively connected to the closing member (4) in order to maintain the open position on the guide bar (3). Said spring arrangement is provided with a first spring element (5, 5') and a second spring element (6, 6') in relation to the respective moving direction. The spring elements are disposed such that the second spring element (6, 6') can be impinged upon only following a predetermined spring travel (a) when the closing member (4) is displaced into the closed position.
